Maybe the reputation points might not mean a lot to most people here, but I don't generally post in areas outside of assisting people with problems, so this means that my points are a fairly good indicator for how many people I've actually helped, and it feels pretty good.

You couldn't find a book title that aligns more perfectly with my blog's mission statement: Seven Languages in Seven Weeks by Bruce A. Tate. It's a whistle stop tour of seven programming languages. Each one is chosen for an aspect of its programming model.

It has come to my attention, both here on DIC and in the real world, that many programmers do not actually know that there is a difference between a switch statement and a string of if-else clauses. This seems worthy of correction. You may have been told at some point in your path to becoming a developer that a switch statement is "just like...

In order for someone to help you to solve your problem you have to help us to help you. First, post the relevant code wrapped in code-tags. Highlight the code and press the [ code ] button just above where you are typing. Press the Preview Post button until it is correct.

Today I'm releasing my free ebook - A Primer on SQL here at Dreamincode. It is a short ebook teaching the basics of SQL assuming no prior knowledge of it. While the examples and text use Ingres as the database management system, the code should work correctly on any SQL compliant database.

Hey guys so I have decided to start blog series where I will be talking about my experiences in Android! Today I will talking about how I calculated the path of enemy units in the game that I am creating. I would like to note that any code that post in this blog entry is still a work in progress and not all the logic bugs have been worked out...

One year ago, I posted a whiny, melodramatic entry about the horrible abuse I was suffering at the hands of my employer when they implemented their mandatory everything-must-use-Joomla-for-a-CMS policy. I am now on the cusp of launching my third Joomla-backed site and, while I'm still not excited by it, I have learned to manage (and in some...

There are a lot of threads about doing homework, and about questions regarding homework. Yet we still get tons of questions for the same things over and over... see the same problems over and over... so I'm going to throw my hat in the ring of trying to cover these in one place rather than have so many people waste so many man-hours saying...

Welcome to another exciting episode! Today we will be discussing a topic that seems to be a bit of a confusing one for everyone... storing BLOB images in MySQL and then showing them again using PHP. While it is always advised against, we will show you a little demo code for how this can be done and discuss why/why not do this. We will then...

You may have heard of minimalism before in all sorts of disciplines and philosophies of life. Some of you might have heard of it as living without many possessions or perhaps in computing to refer to using as least amount of hardware and software resources as possible. I would like to take a small spin on perspective of applying this philosophy of...

I come onto this forum occasionally to check up on things. Mainly to see if the forum is still around in a day and age where Reddit is basically the go to gathering hole for programmers. But personally, I think Reddit is missing something in any of its communities, though I'm unsure what that is exactly.

Hi, first off I’m not a computer programmer or know anything about coding. I really need to be educated in lamens terms and if someone could please help me I’d forever be great full. I was told by someone that I’m in a chrooted environment and someone has wrecked my homestead. I was told I needed a power wash to clear the cride and maybe an...

I saw a couple posts about the Snake game recently, and I realized that I've never actually tried to tackle this game. This post is only about design, so if that idea doesn't interest you, feel free to skip this entry.

Alright, so Snake is played on a grid of W,H where W = some width and H = some height. A snake segment is a 1x1 cell at...

It's eating up 21% of my code time. I only call it 90 times in a certain program whereas some other funtions are used 5000 times. To give you an idea of how slow it is, it is 535 times slower than the...

As I am sipping a cup of coffee and writing this blog post on a Saturday afternoon, I keep thinking about how fast time has passed. I joined DreamInCode on May 16th, 2009, just a few months before going to college. Today, it's May 13th 2017 and these numbers make me realize how much time has passed (not to mention, make feel a bit...
